Estimate the employee-side Social Security and Medicare tax on a paycheck.
Social Security: 6.2% (up to the annual wage base limit, not modeled here). Medicare: 1.45% (no cap; an extra 0.9% applies above high income thresholds, not modeled here).
Illustrative estimate only — tax rules change frequently and vary by jurisdiction/circumstance. Verify with an accountant or official source before relying on this.
